Abstract: A method for operating a syringe pump assembly includes receiving a syringe in an opening of a drug receptacle of a pump of the syringe pump assembly; determining information indicative of the contents of the syringe using a sensor positioned in the drug receptacle of the pump of the syringe pump assembly; receiving drug administration data from a user; determining an appropriateness of the received drug administration data view of the determined information indicative of the contents of the syringe and further in view of patient-specific information received from an electronic medical records system; and making an administration decision for the contents of the syringe based on the determined appropriateness of the received drug administration data.

Abstract: The invention relates to a method for refining a feed oil having contaminants therein. In the method, the feed oil is exposed to reducing conditions at elevated temperature and pressure so as to reduce at least some of said contaminants. The resulting oil is then degassed under reduced pressure under non-oxidizing conditions and the resulting oil extracted with water so as to produce a refined oil.

Abstract: An oral fluid collection and transfer device comprises a collection device (10) and a test cartridge (100). The collection device includes a frame or chassis (14), and an absorbing pad (12) for absorbing oral fluid and which is secured around part of the frame with part of the frame protruding from the pad. A collapsible cover (16) covers the absorbing means and has apertures (68) for the ingress of oral fluid into contact with the absorbing pad. A cap (18) covers the part of the frame protruding from the absorbing pad. The cap and the cover latch together to surround the frame and the absorbing pad. The device also includes a fluid adequacy indicator (20) in the form of an electrical circuit with an LED (66) which is completed when the absorbing means has absorbed a predetermined volume of oral fluid.

Abstract: A storage and work place apparatus used in conjunction with a wheelbarrow or similar item. The apparatus includes a housing having a bottom portion and a side portion extending outwardly to form an open chamber the bottom portion is intended to a lie atop a wheelbarrow a cover is used in conjunction with the open chamber and is hingedly or slidingly attached to the housing in order to extend laterally from the housing. At least a first leg attainably connects to the housing and extends outwardly to contact a ground surface adjacent the wheel barrow. At least a second leg is rotatable attached to the cover and also extends outwardly therefrom to support the cover above the ground surface when the leg contacts the ground surface.

Abstract: A screening device for performing an immunoassay test to detect the presence of a compound in a body fluid. The device includes a holder for removably receiving a membrane to which the fluid has been applied. Light is directed to the membrane. A photodetector measures the concentration of the light reflected back from the membrane. Specifically, the concentrations of reflected light from a control zone and a test zone are measured. Signals representative of the measured light concentrations are applied to a processor. If a specified concentration of predetermined light from a control zone on the membrane is detected, the processor considers the test to be successful. In the test is successful, the processor, based upon the measured concentration of reflected light from the test zone, generates data representative of the presence of the compound.

Abstract: The invention provides competitive immunoassay techniques for high sensitivity detection of delta-9-tetrahydro-cannabinol (cannabis; THC) employing a carrier conjugate of an intermediate in the biosynthesis of cannabis, more particularly 5-pentylresorcinol conjugated to a macromolecular carrier via its hydroxyl groups. By employing such a conjugate with anti-THC antibody in a lateral flow immunochromatography test device convenient on-site testing for low levels of cannabis in liquid samples may be achieved. Such testing is particularly favoured for roadside testing for cannabis in oral fluid samples.

Abstract: A pressurized flushing system for discharging liquid into a toilet bowl. The mechanism comprises a sealed container for storing a pre-determined volume of the liquid under pressure having an inlet for connection to a liquid supply source under pressure and an inlet valve to permit liquid flow through the inlet until the pre-determined volume in the sealed container is reached. There is an outlet for discharging liquid under pressure and an outlet valve movable between an open position to permit liquid discharge through the outlet and a closed position to seal the outlet. The outlet valve is urged by internal pressure within the sealed container toward an open position of the outlet when the pre-determined volume of liquid is in the sealed container, however, an actuator normally locks the outlet valve in the closed position against the internal pressure of the container. Operation of the actuator by a user unlocks the outlet valve to permit movement of the outlet valve to the open position.

Abstract: Immunoassay tests or agglutination tests run on samples of bodily fluid to detect the presence of particular compounds such as drugs in the body may be screened in the screening device. A test membrane is inserted into the screening device and illuminated. The reflected image is detected and the digitized data processed. For immunoassay tests, the digitized data is segmented and data for the test region is compared to that from the control region and the background regions to determine whether the test data exhibits any significant results. For agglutination tests, the digitized data is processed to determine the number and size of the areas of coagulation to determine whether the test data exhibits any significant results.
